This update will feature Nvidia DLSS support with frame generation, display and HDR controls for supported systems, and other optimizations and improvements. You’ll be able to opt-in to try it via the Steam Beta options. We’d love your feedback before it goes live for all PC and Xbox players after that.
Stay tuned for the specifics soon, and thanks for playing!
Also as beta, they must be highly confident with their QA, if the patch only contains exactly what stated.
